Chapter 3 - The Cold Room
The pediatric dermatology team from the ABC Medical Center arrived with the frantic energy of people who knew their careers depended on their speed. Dr. Aranda, a sharp-eyed woman with silvering hair, didn't even look at the luxury surroundings as she entered the stripped-down nursery. Her focus was entirely on the clinical reality before her.
For the next two hours, the room became a sterile battlefield. Sofía assisted Dr. Aranda with the practiced efficiency of a high-level trauma nurse, anticipating every instrument, every swab, and every diagnostic patch before the doctor could even ask for them. They carefully applied the hypoallergenic test strips to Mateo’s upper back, taking small, precise skin scrapings to rule out secondary fungal infections caused by the broken skin barrier.
Throughout the entire process, Mateo cried, but it was the normal, predictable distress of a tired infant being disturbed, not the white-hot, agonizing scream that had filled the mansion for weeks. Whenever the pain grew too sharp, Sofía would sing to him—not a high-class lullaby, but an old, rhythmic folk song her mother used to sing in the kitchens of Iztapalapa. The low, gravelly melody seemed to ground the child, his small fingers locking onto her thumb like a lifeline.
Valeria sat in the corner of the room, her hands tucked between her knees, watching the process with a mixture of intense relief and a profound, hollow grief. She looked at Sofía, who was moving with such grace and certainty, and then down at her own hands—hands that were soft, uncalloused, and completely useless in the face of her son's suffering.
"He really does love you," Valeria said quietly, her voice breaking through the clinical murmurs of the doctors.
Sofía paused, holding a sterile gauze pad over a fresh scrape. She looked at the younger woman, seeing past the expensive silk robe and the hollow eyes to the raw ache of a mother who felt replaced.
"He doesn't love me, Valeria," Sofía said softly, her tone deliberate and warm. "He loves safety. Right now, my clothes don't smell like the chemical that hurt him, and my skin hasn't been associated with his pain. You didn't do this to him. You were trapped in the same trap he was."
Valeria’s lower lip trembled, and she quickly looked away, wiping a tear from her cheek with the back of her hand. "His grandmother... Leonor has always controlled everything. When Nicolás and I ended our engagement, she told me I was lucky she was letting me stay in the house at all until Mateo was older. She said I didn't have the background to raise a Velasco. I thought... I thought she was just being old-fashioned and strict. I never thought she would hurt him."
"We don't know that she did," Sofía reminded her, her professional boundaries firmly in place. "An irritant is often an accident of luxury. People think more expensive means safer. It rarely does."
Dr. Aranda stepped back, dropping her gloves into a biohazard bag. "The initial skin presentation is classic severe contact dermatitis with potential systemic absorption of the preservative. We’re going to initiate a low-dose topical steroid layer, followed by an immediate barrier repair ointment. No fragrances, no dyes, no organic additives. Just pure petroleum and zinc."
The doctor turned toward the doorway, where Nicolás had just reappeared. He had changed out of his suit jacket; his white shirt sleeves were rolled up to his forearms, revealing thick, corded muscles and a jagged white scar that ran from his wrist up into his cuff—a souvenir from a lifetime of violence he never spoke about.
"What’s the verdict, Aranda?" Nicolás asked, his eyes sweeping the room until they settled on Sofía, who was gently applying the clear ointment to Mateo’s legs.
"The nurse was right, Nicolás," Dr. Aranda said, her tone professional but laced with an undeniable respect. "If this child had remained in that environment for another two weeks, the skin barrier would have entirely degraded, leading to systemic sepsis. Whoever introduced that industrial preservative into his laundry cycle was either profoundly ignorant or deliberately negligent."
Nicolás’s face didn't move, but the air around him seemed to drop ten degrees. "Thank you, Doctor. My security detail will handle your payment and your escort out."
As the medical team packed their equipment and filed out of the room, Nicolás walked over to the windows, looking down into the courtyard. The sun was setting, casting long, bloody streaks of crimson across the manicured lawns of Bosques de las Lomas.
"Valeria," he said, his back still turned to the room. "Go to the guest wing. Sleep for eight hours. That is an order."
Valeria stood up, her body trembling with exhaustion. She looked at Mateo, who was now sleeping soundly in a temporary metal medical crib the doctor had provided, wrapped in one of Sofía’s plain cotton sheets. "Is he going to be okay?"
"He is safe," Nicolás said. "Go."
Once Valeria had closed the door behind her, the nursery felt immense, the empty spaces where the luxury furniture had been now filled with cold, clean shadows. Sofía stood beside the crib, her hand still resting on the metal rail, her own body finally registering the immense weight of the double shift she had worked before even arriving at this mansion.
Nicolás turned around. He walked across the room until he was standing less than a foot away from her. He was a massive man, built for intimidation, used to looking down on everyone he met. But Sofía didn't look up with the wide, terrified eyes of his employees or the calculating gaze of his business associates. She looked at him with the steady, tired clarity of a woman who saw him simply as a man with a very complicated, very dangerous life.
"You're exhausted," Nicolás observed, his voice low, almost intimate in the quiet room.
"I’ve been awake for twenty-four hours, Mr. Velasco," Sofía said, her voice steady despite the fatigue pulling at her eyelids. "That is standard for nurses in the public sector."
"You don't belong in the public sector anymore," he said, reaching into his pocket and pulling out a black leather checkbook. He unscrewed a heavy gold pen. "Name your price. To stay here. Full-time. You answer only to me. You care for my son, and I will buy you any clinic in Mexico City you want when he is grown."
Sofía looked at the gold pen, then up at his gray eyes. She didn't look insulted; she looked slightly amused.
"You think everything can be settled with a signature, don't you?" she asked softly.
"In my world, it usually is."
"Well, in my world, Mr. Velasco, a patient cannot be bought. I will stay here until Mateo’s skin is completely healed and his mother is capable of taking over his care. You don't need to buy me a clinic. You just need to pay the standard agency rate to the General Hospital so they can hire two temporary nurses to cover my shifts while I’m gone."
Nicolás stared at her, his pen hovering over the paper. For the first time in his adult life, a negotiation had broken down before it even began, not because the counter-offer was too high, but because the currency he was offering was entirely worthless to the person across from him.

"You're a very stubborn woman, Sofía," he murmured, using her first name for the first time.
"I’m a nurse, Mr. Velasco," she said, turning her attention back to the crib to adjust the edge of Mateo’s sheet. "We don't have time for anything else."
